Li Hongxia, born in October 1965, serves as an academician of the Asia Pacific Academy of Materials, director of the National Key Laboratory of Advanced Fire-Resistant Materials, and chief scientist at China Baowu Steel Group. She received her Bachelor’s and Master’s degrees from Tianjin University in 1987 and 1990, respectively, and earned her Doctorate in Engineering at the Shanghai Institute of Ceramics, Chinese Academy of Sciences in 1994. From 1992 to 1993, she was a visiting scholar at the University of Michigan in the U.S. In 1997, she served as a researcher at Japan’s Okayama Ceramic Research Institute. Renowned for her work on metallurgical fireproofing materials, Li has also been recognized as a National Model and awarded as one of the first National Prominent Engineers.
Q1: In 1983, you began your studies in materials science at Tianjin University and continued for seven years. Could you share your fondest memory from that time?
Li: The most memorable experience during my time there was actually failing my first math exam in freshman year. Of the thirty students in my class, nearly half of us failed. We weren’t fully adjusted to college-level learning, which required new study techniques. Some of us attributed our failure to the exam’s difficulty, but that was only part of the problem, as others did pass.
This failure was a turning point for me. During the Spring Festival, I received a letter from the school notifying me of the upcoming make-up exam. This was a wake-up call—I realized I needed to adapt my study habits, to be more disciplined and proactive. My roommates and I started reserving seats in the front rows to help us stay focused. This change paid off, and I was honored as a “Three-Good Student” for three consecutive years.
Moreover, college broadened my perspective in unexpected ways. My peers and I often engaged in deep discussions on philosophy, including ancient Chinese civilization, which significantly shaped our outlooks. We also delved into Western technological advancements, and I became acutely aware of the technological gap between China and other nations. This experience highlighted for me the crucial role that science and technology play in national development.
Q2: What has been the greatest influence on your career?
Li: When I entered college, my major was technical ceramics. Initially, I thought I’d be studying basic ceramics, like pottery, and was reluctant to attend. However, one of my high school physics teachers assured me that this major had promise and would involve advanced materials like capacitors and sensors. This sparked my interest and shaped my path in technical ceramics.
During my master’s studies, I had the privilege of working with Professor Yuan Qiming, who earned his degree in the UK and specialized in structural ceramics, particularly zirconia ceramics. His approach to research was transformative; rather than focusing solely on publishing, he emphasized applying scientific findings to practical and economic uses, which profoundly influenced me. He led a significant national project on ceramic engines and other applications, embodying the school’s spirit to “make solid efforts to reshape our nation.”
Another key influence has been the patriotic spirit shared by all Tianjin University students. The university motto, “Seeking truth from facts,” encourages us to serve our country by applying our knowledge to real-world challenges. As a former chief engineer and now chief scientist at China Baowu Steel Group, I strive to apply my research to benefit China.
Q3: You spoke at the 2021 graduation ceremony, expressing your commitment to a prosperous and strong China. Could you offer advice on making life choices to young people based on your own experiences?
Li: University provides fundamental training, instilling in students a method for learning and a framework for conducting research. In addition, the rich cultural environment fosters honesty, sincerity, and resilience. Professor Yu Guozong at Tianjin University set a strong example for us, demonstrating courage, resilience, and a steadfast dedication to national needs.
Life is full of choices, none of which are inherently right or wrong; the best choice is the one most suited to your personal journey. After making a decision, stay committed to giving your best in your field. Beyond that, think about how to make valuable contributions to society, drawing insights from textbooks, real-world experiences, mentors, and teamwork.
I often reflect on my own work and studies, which enhances my thinking. Learning with questions is essential, as is repeatedly asking “why.” In research, we aim to uncover what lies beneath the surface, step by step.
Q4: Tianjin University focuses on cultivating top engineers with an emphasis on new engineering. In your view, what qualities make an excellent engineer? Any advice for those aspiring to this career?
Li: The essential quality for an engineer is the drive to practice, as echoed in our school song’s lyric, “Never be an armchair strategist.” Engineers must focus on the market and emerging technologies, gaining firsthand experience to understand market needs. An excellent engineer engages in technological innovation while also considering the underlying scientific principles. This requires courage to take responsibility and pioneer new ideas.
Interdisciplinary learning is also critical, particularly with the rise of AI and big data. In material technology, past trial-and-error methods are being replaced by data-driven research. This change improves research efficiency, shortens project cycles, and reduces environmental impact. Our university needs to introduce courses on these new technologies, benefiting both students and faculty. By learning together, we stay aligned with scientific and technological advances.
Furthermore, openness and collaboration are vital. Personally, I often ask myself, “Who am I working for?” This reflection sharpens my focus on the requirements and expectations of those I serve. I hope that Tianjin University continues to carry forward its legacy of excellence in engineering education, and I am confident that we can achieve even greater success.
Q5: Next year will mark Tianjin University’s 130th anniversary. Do you have any suggestions for its future development?
Li: We should continue to highlight our university’s unique culture and soft power, as it embodies the values that define us. Our nation is at a pivotal stage, and achieving national rejuvenation requires scientific and technological breakthroughs. Tianjin University is well-positioned to leverage its strengths and discipline advantages to address our country’s urgent needs. I am confident that the university will continue to excel, contributing to our nation with enduring strength and a spirit of openness.
